T0 azz w /wm 7175 m-ay coowern Be it known that I, THOMAS J, lTJA'VEIRE2L oitizen of the Unieecl StaceS 1esiding ot Bethel, in the county of Windsor ancl Stae of Vermont, lmve inventecl oertain 11ow ancl useful llmprovoments in Fluo Cleanercs, of Which the following is a speoification.

This invention relates to oleaning apparatus and has for an objeot to proviclo a cle* vice tlmt is especially adaptecl for oloaning chimney fiues Another object of tl1e invention is to provicle a clevice adapted for oleaning ohimneys baving small orookecl flues but whioh is adjustable for clifferent sizes of fiues.

A further objct oi the invention is to proviole a fiue cloaner Wl1ich is simple and durablein construotion, inexpensive to manu faoture ancl of'flciont.

These am] such other objeots as mzmy he1e inal'ter appezmare attaino(l by tho novel com- :stn1otion oombination und zur1m1gement 0'l. arts to be hereinafter speoifieally desoribecl ancl claimecl.

Reference will now bo l1ad to the 21000111- panying clrawings forming a part of this speoification, wherein:

Figure 1 is a sitle elevation of tho -complete device.

Figu1e 2 J's an eml viow 0'l tbe clevice.

Figure 3 is a transverso sertional view m :on on the line 3 3 of Figuro 1 an l lookin, in ltbe direotion of ehe arrows.

Figu1o is (1. detail view o? ono o'l l;ho oleaning elements.

Throughout the following detailecl (lesoripzion ancl 011 the several figures of tho lrawingsimilar Parts a1e referred 140 by like reference clmraoters.

Referring to lihe drawings, the reference numeral 1 inxlioutes 21 support oonoisting of an oblong: block of l'lll'fl wood l1avinog ils lon gitudinal edges boveled. as indlcatecl by be r-oferenoe numeral 2 Fastenecl in tl1e Sicles anal bevelol eclges of tl1e supporting block am a plumliy of oleaning elements Eaol1 element consists of apieoe of spring steel wire formocl wltb 21 loop 4 intormecliate its ends, one end of tl1e olement being screw-threadecl. Euch element is zuljusably fastenecl to the block by being sorewed therointo unoil its loop. portion engages in a slot 5 in the blook be interlooking engagement of the loop in the slot preventing the element from turning relalive to the block when in use It will bo 1iotd that due tothe resilionby of alle material out of whioh the element is macleit can bo soriawecl oloWn into the block until a firm int'erlocking ongagement is lmdbetween fl1e loop a1icl slot.

The eloments Seouiecl in the bevelerl eclges of the block project further from the block than Elle elemnts seourecl in the sicles thereof so that in use the ele1nents secured in t-he bevolecl edges woulcl scrape the oorners of a flue ancl the elements seourecl in the sides of the block would scrape the sicles 01" the flue.

'Owinp; to oho screw-threadecl connection of the elements to the block they can be iacljusted within limits so as to inorease or decrease the size of the cleaning clevice to cor= respond with the size of the flue to be cleaned whilo maintaining the interlocking engagement between the loops ancl slots.

Sorew-oyes 6 are securecl in tbe opposite ends of the block, one for the ataohment of' 2.L weight und the otbor fo1' be attachmont of a rope. k

The manner 0f usingthe devlce is as follows: Tho elements 3 Will be adjusted in the block so that the clevioe Will properly fit the particular flue to be cleaned. A weight Will tben be attaohecl to the screweye in 0ne end of the blockand a rope to the soreweye in t-he o'therend. Tho clevice can be inserted witbin the flue from the fop thereof, the

weigbt-cnrrying tho clovice Clown into th6 fluo and .pausirig tbo olements thereof to sorapo tbe fluo. By moans of the rope ancl weight tho device czm be reoiprooatecl in the flue until the clezming elements 8 have clis loclgecl substantially all th e sootdepositecl therein anal czmsecl it to d1op into tlle bottom thereof.

Havinp; thus clescribed my invencion, what Iclaitn a s new ancl clesire. to secure by Letters Patent is:
